Fig. 6 is a schematic elevation of a reel illustrating the skein pattern.

While my invention may beembodied ina single reel layout, I have indicated portion of la commercial installation in which a plurality of reelv units are supported upon a longitudi-V nal channel 15, each unit mounted thereon comprising a pair of reels, oneon Ieach' side of the channel, The supporting frame of each unit comprises a plate-like casting 16 resting a side elevationl thereof partially on the channel 15 and having arms 17kand 18 Y whi-ch extend on opposite sides thereof,each

arm carrying reels 19 and 2O and their associated mechanisms. Since the mechanisms are alike, it suffices to describe onlyfone.

The drive of each reel is effected 'by a belt 21 from a pulley on a shaft (not shown) arranged longitudinallybeneath the channell. Each belt 21 engages a pulley 22 loose on a shaft 23 (Fig. 3) and provided with a pin 24 adapted to engage lugs 25 on a clutch hub 26 sliding' ona feather 27 on theshaft 23. At the opposite end of the shaft 23 is pinned, or otherwise secured, gear 28 2) `meshing with gear 29 pinned at 3 0 to the hub 31 of the 1927. Serial No.' 207,164.

reel (19 or 20). The 'details of the reel construction do not enter into the present invention. but are described in the copending application of Thompson, Ser. No. 201,526, tiled June 25, 1927 patented May 28th, 1929, No, 1,715,315.

The clutch hub 26 is displaceableon the shaft 23 against the actionof spring`32 by' the fork arm 33the hub 34 of which is fast with the pin 35, supported in lthe boss 36 of the frame and passing through the fixed cam member 3 7 and the hub 3S of operating lever 39. The hub 38 of the operating lever is provided with a pair of cam bosses 40freceived in corresponding notches 41 in the adjacent face ,ofthev block 37. vWhen the lever 39 is swung outward in the direction of the arrow the bosses/40 ride out of the notches 41 in block 37, thus displacing the arm 33 sufiiciently to shift the clutch hub 26 away from. thevpulley 22 and thus break the drive engagement of the pin 24 of the pulley with one of thebosses 25 on the hub. A recess 42 formed in the'block 37 to one side of the notch 41v aords a slight shoulder which latches the lever in open-clutch position. To re-establish the drive of the reel, lever 39 is moved in theopposite direction, risingout ofthe recess 42 and; dropping into the notch 41 under.

the stress of the spring 43 engaged between the inner face of the block 37 and the collar 44 on pin y Y The clutch lever 39 is employed bythe operative to halt the drive of the reel during the skeining operation, in case of breakage of the thread, so that the ends of the thread may be knotted and the skeining operation renewed. K 1 During the skeining operation the thread is guided by a .traverse motion to form anl ,open diamond pattern 45 (Fig. 6) on the reel, n

the partsbeing so related that on successive oscillations of the traverse, alternate courses coincide with substantial precision. The diamond pattern thus formed on the reel facilitates the insertion of the usual lacing thread,

`provided the openings 46 of the pattern are accurately maintained during the skeining operation. Thlshas not been the case, however, 1n skeining mechanisms of the present general type heretofore in common use. In such prior mechanisms the arrangement of parts is such that in case of interruption of the reel drive during skeining, in order to repair a broken thread, the initial relation between the traverse and the reel becomes changed, so that after the repair is made and the reel is again put in operation, the delivery from the traverse to the reel is not coincident in its courses withthose followed by the thread prior to the interruption. Consequently, the openings 46 in the skein pattern on t-he reel have been at least partially filled by the new courses. lacing operation is performed, the operative must make openings in the skein for the lacing cord. This is very apttto cause Vbreakage'of the thread in the skein. Y

.The present layout so relates'tlie traverse mechanism to the reel that their relation is maintained with precision, regardless of stopf page by the operative during the course of theskein winding.

For this 'purpose the traverse drive is taken from the reel through gear 47 fast with the reel gear 29. Meshing with the gear 47 is a gear 48 which carries a crank pin 49 engaged by the connecting rod 50. Thexopposite endv of the latter is hinged at 5l-to one end of al rock lever 52, the opposite end of which is fast with aV vertical rock shaft 53 which passes down through the channel l5. `Secured to the rock shaft below the channel is a traverse' arm 54, the freeelnd of which supports abar `55 carrying the thread guides 56. In the present instance the reel armsare of suiiicient length to permit the formation of .two skeins simultaneously thereon. Each traverse'bar 55 consequently carriestwo thread guides 56. It will be noted that when the drive 1connection from pulley 22 to the reel is halted during the Yskeining operation, there is no break inthe drive connection of the traverse from the reel. Nor is there any alteration in the relation between these parts aslias heretofore been the case. Consequently when the drive of the reel is resumed, the traverse arm resumes its motion at precisely the same point, with respect to the reel, at whichthe operation is halted. Consequently the diamond pattern of the courses on the reel is maintained with precision, and the openings 46 are kept clear of obstruction by floating threads. The-lacing cords may thereforebe inserted without danger of injury to the skeins. j, I Valso provide an automatic stop for halting the drive of the reel after a predetermined number of revolutions to maintain uniformity in the length of thread wound in'each skein. For this purpose I use a clutch operating rod 57,*provided, at its clutch-operating end, with a block 5S in which an arcuate slot 59 is pro- Y vided to receive lpin 'projecting from the upward extensions 61 ofthe clutch-operating As va result, .when the f leverV 39. The lost motion engagement between the rod 57 and lever 39 through the pin and slot engagement 59-60 between these parts, permits the manual operation of the clutch lever 39 to open the clutch, without disturbance of the rod 57. Y It will be noted, however, that when the clutch is manually closed, the pin 60 lies atthe outer end of the slot 59. Upon automatic displacement of the rod 57 in the direction of the arrow y/.thercfore, the lever 39 is swung in the direction of the arrow a@ and thus opens the clutch.

To actuate the rod 57 I provide a spring 62 (Fig. 4) anchored at 63 to the frame, and at 64 to the rod 57. The spring 62 is constantly under tension. The rod 57 is held against the displacing effort of the spring 62, however,-by a stop block 65, against' which a shoulder 66 on the rod bearsl A saddle 67 pressed by spring GAS-against the opposite face of the rod, tends constantly to force the shoulder 66 into engagement with the stop block 65. Sufficient play between the rod and the block is provided, however', to permit 'the shoulder to move against the action vof the spring 68 a sufiicient distance to clear the block 65, whereupon the spring 62 thrusts the rod 57 in the direct-ion of the arrow 'y to operate the clutch.

To free the rod from the block 65, and permit its displacement in the directionof arrow Yfz/ by spring 62 (and thus to openwthe clutch as above explained) I-provide'a rotating snail cam 69 fast on shaft 70. As the cam rotates,its nose 7l engages the beveled end 72 of the rod 57 and displaces the latter' slightly against the effort of spring 68 to free the shoulder 66 from engagement with The effort of spring-62 now forces y to pass out of engagement with the end` of the rod, whereupon the latter drops into the notch 7 3 Yof the cam. This notch is of sufficient depth to afford enoughlongitudinal 'displacement of the rod to swing the lever 39 to open-clutch position-thus automatically halting the reel drive. After the skeins have been laced and removed from the reel, the

operative swings the hand lever 39 inward (opposite to the direction of the arrow thus pulling the rod 57 outward against the effort of spring 62 until the shoulder 66 reengages the block 65, simultaneously re-establishing the reel drive.

The cani 69 and its shaft 70 are driven from the reel through worm 74 fast on the shaft of gear 48 and meshing with helical gear fast on shaft 76. At the opposite end of the latter is a worm y7 7 meshing with helical gear y78 fast on the cam shaft 70." Inasmuch as gear 48 is in the train driven from the reel, the rotation of the latter gradually brings the nose 7l of the cam 69 into operation, and the gears are so related that the cam releases the rod 57 to open the reel drive clutch after a predetermined length of skein has been wound on the reel.

The mechanism' as a whole is simple, selfcontained and compaet,free from trappy operation, and difficult to disorder. The gear drive of the traverse and timing mechanism from the reel without interruption or alteration of the position gearpconnection on the halt of the reel, insures accuracy in the length of the thread wound into the skein, maintains the thread pattern of the skein on the reel, and facilitates the lacing operation without danger of injury to the skein threads. These and other advantages resulting from theinvention may be obtained in various modifications which embody the thoughts underlying what I claim as my invention.
